I've used the same bristle brush to position decals for over 40 years, This tool is good, could use a finer tip which you can trim yourself if desired. Should be avail at any drugstore manicure section. Still prefer my old brush for delicate old decals.

this is way better than using a knife blade to place decals without them being torn

This tool makes placing decals easy and helps take out the stress. I highly recommend this tool for your decal tool.
